Question

Explain how time quantum value and context switching time affect each other, in a round-robin scheduling algorithm.

Answer 1

There is an inverse relation between time quantum and context switching in a round robin scheduling as very high time quantum may lead to starvation , i.e. , other processes have to wait to more. If time quantum is small then there will be more context switching and more process will get time to be executed for lesser time period .
